Problem 26
Describe two ways that glacier ice can move across the surface.
Problem 26
Classify the following as erosional or depositional features: loess, cirque, \(U\)-shaped valley, sand dune, abraded rock, striation, and moraine. Performance Activities
Problem 27
How is creep different from most other types of mass movement? Explain the forces that cause creep, as well as the effect of creep.
Problem 27
Poster Make a poster with magazine photos showing glacial features in North America. Add a map to locate each feature.
Problem 28
Create a chart to show how continental glaciers are different from valley glaciers. Include their causes, physical features, and geological effects on the land.
Problem 29
Slope Gravity is a very powerful erosional force. This means the steeper a slope is, the more soil will move. A person can calculate how steep a slope is by using the height (rise) divided by the length (run). This answer is then multiplied by 100 to get percent slope. If you had a slope \(15 \mathrm{~m}\) high and \(50 \mathrm{~m}\) long, what would be the percent slope?
Problem 30
Traveling Sand A sand dune can travel up to \(30 \mathrm{~m}\) per year. How far does the sand dune move per day?
